The figures given by rotorrookie are truly from a rotor rookie
Well Nick I got these figures from that website without taking a second look but when I run over them again I see that 2-3kg/hp isn’t even close to modern piston engine (more like flathead hurricane engine from 1940´s jeep)
If we use figures from the comparison sheet on the Delta hawk website for Lycoming360 that says it weights 148kg we have power/weight ratio around 0.74kg/hp
So if the numbers for the Randcam being 0.34kg/hp is true, they got great advantage over piston engine, but they probably not even half way down the path and I doubt this will be the same number they end up with when reach the far end, if they ever will.
p.s. Nick I promise to be more precise next time, don’t want to be rotorrookie forever
